IMPROVEMENT IN GRAlN-THRASHERS AN D SEPARATORS.

The Schedule referred to in these Letters Patent and making part of thesame.

in section;

Figure 2 is a transverse section on the line a: aof fig. 1; and

-Figure 3 is a side view of a portion, at the front end.

Thegeneral form and construction of myimproved machine are the same asthat heretofore patented to Gill 8:; Huminell; and are sufiicicntlyshown by fig. 1.

My first improvement consists in hinging to the front edge of the case,at the opening where the grain is fed to the cylinder N, a leaf orapron, A, it being arranged to hang inclined, as represented in figs. l,and 3, the object of which is to prevent the shelled grain. from beingthrown out in the face of the attendant, and, at the same time, to risewhen necessary, to admit bunches of tangled straw in feeding themachine. It will be observed that the positionof this apron is suchthat, as soon as the bunch of grain orstraw has passed into the throatof the machine, it will fall by its gravity to its original position.

Underneath the cylinder I place a backwardly-inclining chute, n, whichreceives the thrashed grain as it falls from the cylinder, and conveysit to the sieves in the shaker D.

The rear end of this shoe I support on a strap, 0, which passestransversely across. the machine, and

has-its outer ends secured to brackets, B, fastened upon the outside ofthe case, as shown in fig. 2.

The strap is held in place at each end by means of a plate, a, which isfastened to the bracket by a bolt and thumb-nut, b,-th e strap beingclamped between, as represented in fig. 2.

At'its rear end this shoe nis provided wit-ha tap pet, 0', which is, hitby a projection, 12, on the front end of the shaker D, which imparts tothe shoe a shaking movement vertically, thus assisting to feed the grainto the sicvcs with regularity. By adjusting the strap 0 so as to raiseor lower the rear end of the shoe n, it will be shaken more or less; andthus grain that is damp is prevented from clogging on the shoe.

The shaft It is provided with a series of cranks, to which is attached aseries of vibrating bars, 3 as in the former patent, these latterplaying between a series of stationary bars, s, as shown in figs. 1 and2.

In the stationary bars I pivot a series of bent arms or agitators, H,each of which has projecting from its side a pin, 1, and on the top ofthe vibrating bar y I locate a block or projection, in, in such aposition that, as the bars y are raised, the projections in will strikethe pins Z, and, thus give to the arms H a quick upward movement, thusshaking up the straw as it passes over them, and thereby effectuallyshake out the thrashed grain.

-There are two series of these arms H, located-as shown in fig. 1;aud'betwecu them I suspend, from a rod, 0, placed transversely acrossthe case, near-- its top, a series of swinging arms, I, which serves todetain the straw, temporarily, while it is thoroughly shaken up by thefirst series of arms H, the arms or detainers I being raised by thepressure of the straw against them as it is forced forward by thevibrating bars 3 as represented in dotted lines in fig. 1.

Upon the outer end of the crauk shaft R. I secure a wheel, 1?, as shownin figs. 1 and 2, and from the outer side of this wheel there projects apin, 0, which, being located eccentrically,operates as a crank orwrist-pin.

This pin 0 plays in a slot in the end of a lever, O, pivoted to the'sideof the case upon a stud, f, the lower end of the lever being connected,by a rod, (Z, to an elbow-lever,'g, which latter is in turn connected bya link to the shaker I), in the usual manner. This arrangement ofdevices imparts to the shaker and its sieves a' sudden vibratingmovement,- aud thereby thoroughly shakes the grain on the sieves, andscreens it most effectually.

Under the straw-carrier or bars y I locate an inclined bottom orchute-board, G, as shown in fig. 1, this bottom inclining from the reartoward the front, and thus receiving the grain and chafi" that is shakenout of'the straw above, and delivering it upon the rear end of the shoe'Hl.

At each end of this inclined bottom G I placea transverse shaft, t, andaround them and the incline G I stretch a couple of endless bands, F,one at each side, having 'a series of small bars or slats secured tothem transversely, as represented in fig. 1, thus forming a carrierwhich, when set in motion in the direction indicated by the arrows,carries or sweeps along on the incline, at regular speed, all the grain,chaff, hcads, &c., that may fall upon it. By this means the grain andchatf are delivered, in a steady and regular flow, to the action of thefan and sieves, andare prevented from accumulating in heaps on theincline and falling therefrom in bunches, as they would otherwise be aptio'do.

The cylinder is driven by a belt, Q, from any suitatznt (tffim ablepower, as represented in fig. 3; and from a pulley on the'opposite endof the cylinder-shaft a belt extends to the fan-shaft Z, on the oppositeside of the case, as represented in dotted lihes; and from a pulley onthe opposite end of the fan-shaft another belt, t, extends to the loosepulley P on' the crank-shaft B.

On the shaft is placed a sliding clutch, t, as shown in fig. 2, and onthe side of the case I pivot a lever, E, as shown in fig. 3, foroperating the clutch, the end of the lever being in convenient reach ofthe person who feeds the machine, so that he can disengage the pulley1?- whenever desired. Then this pulley is disengaged the motion of allthe parts except the cylinder and fan ceases, and, consequently, nochafi" or other material, is then fed tothe sieves or falls into thegrain-box uncleaned, as would otherwise be the case in stopping andstarting the machine after it was once in operation. By these severalimprovernentsthe machine is made to operate in a much better manner,and, therefore, producing better results.

- Having thus described my invention,

What I claim is 1. The inclined shoe on, having its rear' end sup portedby the adjustable strap 0, substantially as set forth.

2. The bent arms H, provided with the pin 2, said.

arms being pivoted to the stationary bars 8, and operated by thevibrating bars y, as herein described.

3. The arrangement of the slotted lever O, with its operating wheel Pand elbow-lever g, and connectingrod (1, foroperating the shoe D, as setforth.

4. The combination. in a thrasher of the inclined chute Gr, with itsendless carrier F and the adjustable chute 12', when arranged asdescribed, whereby the grain from the cylinder and that from the shakershall all be delivered from the chute n to the shoe D, as set forth.

5. The combination of the hinged detainer arms I, stationary bares, andvibrating carrier bars y, all constructed and arranged to operatesubstantially as described.

6. The crank-shaft It, having the loose pulley l and clutch i mountedthereon, with the lever E, arranged as described, whereby the shaker andshoe D are thrown out of connection with the driving-power while thecylinder and fan are permitted to continue their motion, as set forth.
